China lab suspected of Covid leak stripped of US funding for violating biosafety rules
(www.telegraph.co.uk)
It came from the wild. They, along with Germany and other labs, were researching Sars related wild vectors and the possibility of natural selection causing a new outbreak.
I find it reasonable to believe a biosafety incident at the Wuhan lab infected several of the lab researchers and that led to the pandemic.
But that's the extent of where things go. Conspiracies about bioweapons are idiotic.
